Extremely slow, cpu hog with .csv files

[SurlyJest]

I've just noticed a very undesirable problem with 7.4.0 (64 bit) under Win7(64). When I try to open a comma-separated values (.csv) file the program takes forever to load it and even then sits there using some 25% (of 4 CPUs) and becomes so unresponsive that the only way to end it is by killing through the TaskManager.

This is weird, because I don't have any problem with very large log files, and even word-wrapping on a 200MB file isn't this bad. So far, these are quite small - just 20-40K. I know I used to work with quite large CSV files with 32 bit versions (some time before - as far back as whatever was current in 2008). I've got plenty of memory (8GB) in a laptop with SSD drive and pretty recent 2.8Ghz i5-3369M Intel chip. There's just no excuse for this from a hard-drive.

I know it isn't a line-wrap issue - I created a document class for .csv files and made sure the Wrap Long Lines option was unchecked. The big difference since the last version I had is this is my first 64 bit TextPad (been using it since forever, it seems - certainly since I had to pay for a version upgrade to 5.x).

Has anybody else seen this? I can't be the only user that that kind of file...
In the meantime, if I get time, I'll try a downgrade to 7.3 and/or 7.4 32 bit.

Thanks in advance.

No problems here. I just now opened a 44 MB .csv file with over 13K rows. Opened in a matter of seconds. And I've got Outlook (which is a hog), Chrome, and SSMS open as well.

TP 7.4 (64 bit) running on Win7 Ent, 8 GB RAM, I think it's a 1 TB SATA HD (so your SSD is better than mine), and 3.4 Ghz Intel i7-3770 CPU (which is better than yours).

How did you open it? I did a right click on the file in Win Explorer, and selected TextPad from the Context Menu.

When I try to open any file from the context/right click menu, it takes forever.

Any idea why?
